` To all whom it may concern."

Be it known that I, JOHN K. HAUBERG, a citizen of' the United States,and a resident of Cando, in the county of Towner and State of NorthDakota, have invented an Improvement in Metal-Rolling Machines, of whichthe following "is a specification.

My inventfon is a' machine by which iron vor other metal plates arerolled under pres sure and thus drawn out, tapered, or beveled to anyrequired degree.

A distinguishing feature is a roller carried by a. reciprocating frameand adapted to act on a heated metal plate while held on an anvil block,and mechanism for adjusting such block higher or lower, or at dilerentangles, according to the bevel it is esired to impart to the plate.4 Themachine enables this resultto be attained quicker than it can bedone byhand, thus saving time and labor, besides doingv the work better. 4

The details of construction, arrangement, and operation ofthe machineare hereinafter described, and illustrated in the accompanying drawings,in which* Figure 1 is a longitudinal-section of the workingJ parts. Fig.2 is a side View.` Fig. 8 is an end view. Figs. 4 and 5 are crosssections 'on lines 4-4 and 5 5, respectively, of Fig. 1. Figs. 6. and 7are longitudinal sections on lines 6 6 and 7-7, respectively, of Fig. 1.v

As shown in Figs. 1 and 2, the Y-shaped slotted frame 1 to which theoperative parts are applied is mounted and secured upon a base frame 2having an inclination of about 30 to the horizontal. The upper and lowerportions or jaws la and .1b of the frame are parallel and `separated bya considerable space between which the rolling mechanism proper isarranged. A crank shaft 3, provided with a balance Wheel 4, is journaled inl the small end of the Y-frame, and a pitman 5 connects itwith a bar or thick plate 6 which'is supported Vby suitable means fromthe upper jaw la, and between' it and said jaw is arranged al series ofsteel antifrict-ion rollers 7 which are journaled in a frame 8 andadapted to work in contactwith a steel wearlvplate 9 that forms theunder face of the upper jaw 1a. The frame 8 .is extended toward thecrank shaft and is .operativelyconnected with the pitman 5 by means of alever 10`f'whose fupper end is connected #A i "r i with the jaw 12l bymeans of a link 11. The extended portion or shank of'the frame 8 slidesthrough a keeper or block pivoted to the central portion of the lever10, and spiral springs 12 are arranged on opposite sides of ,this block.It will now be apparent that, b v' the rotation of the crank 3, the baror plate 6 is reciprocated and that the rollers 7 are also caused totravel back and forth in the space between said, plate and the facingblock 9 of the jaw..

A roller 13 having a central circumferential rib is journaled in a shortcarriage 14 which is provided with` inwardly projecting flanges at 15that slide in grooves 16 formed in the sides of the bar or plate, 6,before described. This roller works in contact with the under side ofsaid bar or plate 6 and is thus rotated by friction therewith; but italso has an independent movement due to its connection'with the pitman 5through the medium of the following mechanism. A lever` 17 is pivoted tothe pitman and its lower end is connected with the trame by a link 18. Arod or bar 19 is pivoted to the carriage 14 ofthe roller 13 and itsextended portion 0r shank slides through a block that is pivoted at thecenter 20 of the aforesaid lever 17; and spiral springs 21 are arrangedon opposite sides of said block. so that the action of the .lever on theroller is, so to speak, cushioned.

On the lower jaw 1b of lthe if-trame is arranged a wedge 22, and asmaller wedge Q3 lies thereon, both wedges being adapted to reciprocatetoward or from each other. For adjusting or sliding the larger wedge Q2,it is connected by links 24 with an elbow lever Q5 which is, in turn,connected by a link 26 with a foot-lever 27, which is adaptedvto engagea ratchet bar 28 by which it may be held down in any position to whichit` may be adjusted by pressure applied by means of the `foot. When thelever 27 is released. a spring 29, encircling a rod 29a, which slidesthrough a keeper, Will restore or slide the wedge 92 back to its formeror normal position. The smaller wedge is connected by links 30 with anelbow lever 31- which is, in turn, connected by a forked link 32-with afoot-lever '33, which is pivoted yto a leg of the base 4trame 2.- Aspiral spring that the spring'encircles. It is obviousthat 110 and holdit in, normal position aftervthe-` this spring serves to restore theblock to,l

operation of the foot-lever 33.

An anvil block 34 is supported upon the wedges 22 and Q3- and adapted tobead-- jnsted higher or lower or with its face at i different angles, byadjustment 'of thewedges. The block is held in place by'a pinrunningthrough it and projecting on the sides, as indicated at 35,' thepin working in slots or grooves in the frame, so that it has a verticalplay and also ,allowsthe block to swing in a vertical plane .or adjustitself with the. tace at 'different angles. In other lwords,'the blockmay be adjusted to any vertical or angular position desired through themedium 'of the wedges 22 and 23, so

l that a metal plate may be drawn out or tapered to any thickness orbevel desired. It will be understood that the roller 13l is made oftempered steel and that the central.

times imposed.

rib is the portion which works in direct contact with the plate held onthe anvil 34.

It. will be apparent that. when the plate or bar to be rolled is placedunder the roller y13,' the. latter is forced up against the bearingplate or bar 6, which is moved forward and back 'by rotation ot thecrank-shaft 3, which, in turn, reciprocates the roller over vthe surfaceof the material, and it is at the saine time revolved, which has theeiiect of drawing out, tapering, or beveling thevmetal plate. The roller13 travels one-half the distance that the bearing plate 6 travels, andthe steel rollers 7 travel 'one-half the .distance of the said plate.'In other words,

toward or from each' other according as itA is desired to raise or lowerthe anvil block 34 or adjust its upper surface at different angles,according to the thickness of the plate to be rolled or the bevel to beimparted to it.
